Injection of solids into liquids by means of a shrouded supersonic gas jet |
摘要 |
A method of introducing a solid particulate reagent into a bath of metallurgical liquid comprises a step of introducing a solid particulate reagent into a main supersonic gas jet. The main supersonic gas jet is directed at the surface of the bath and is surrounded with a jet of shrouding gas, preferably of a burning hydrocarbon fluid fuel, provided at a supersonic velocity. The main supersonic gas jet is formed at a velocity which is in the range of minus 10% to plus 10% of the velocity at which the jet of shrouding gas is formed, preferably in the range of Mach 2 to 3.
